Yes, Give up on Spike and Peachtree.

I have the same setup (In fact, I wrote that very wiki page), and have
never been able to get Spike, Peachtree, Movie Central or Super
Channel to work, even when I was subscribed to them.

The multicast stream is deliberately sent "Garbled" on these streams -
Part of the stream data is overwritten with FFs. I believe there is a
second stream coming from somewhere, possibly unicast though I can't
see it, or some code in the box's firmware, that can replace these
missing parts.

Without that data, all you get is (as you see) a garbled and
unwatchable stream. And this list probably isn't the place to talk
about decoding that stream, as the US-based owner and members would
not like to be potentially slapped with a DMCA lawsuit (Though this
would probably be covered under the interop clauses).
